Hu S, Lu Y, He X, Zhou Y, Wu D, Tucker JD, Yang B, Tang W. Effectiveness of the secondary distribution of HIV self-testing with and without monetary incentives among men who have sex with men living with HIV in China: study protocol for a randomized controlled trial. BMC Infect Dis 2023; 23:160. [PMID: 36918824 PMCID: PMC10013267 DOI: 10.1186/s12879-023-08062-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 02/07/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND The HIV epidemic is still expanding among men who have sex with men (MSM) in China, but HIV testing rates remain suboptimal. Network-based interventions, such as secondary distribution, have shown promise to expand HIV self-testing (HIVST) among partners of MSM living with HIV (MLWH) but have not been widely implemented. Monetary incentives could enhance the secondary distribution of HIVST in some settings. We will conduct a randomized controlled trial to examine the effectiveness of monetary incentives in expanding the secondary distribution of HIVST among MLWH in China. METHODS We will recruit 200 eligible participants at three antiretroviral therapy (ART) clinics in China. Participants are eligible if they are 18 years of age or over, assigned as male at birth, have had anal sex with men, are living with HIV, are willing to apply for the HIVST kit at ART clinics, and are willing to provide personal contact information for follow-up. Eligible participants will be randomly assigned in a 1:1 ratio to one of two groups: standard secondary distribution group and secondary distribution group with monetary incentives. Participants (defined as "index") will distribute the HIVST kits to members of their social network (defined as "alter") and will be required to complete a baseline survey and a 3-month follow-up survey. All alters will be encouraged to report their testing results by taking photos of used kits and completing an online survey. The primary study outcomes will compare the mean number of alters and newly-tested alters motivated by each index participant in each group. Secondary study outcomes will include the mean number of alters who tested positive, the cost per person tested, and the cost per HIV diagnosed for each group. DISCUSSION Few studies have evaluated interventions to enhance the implementation of secondary distribution. Our study will provide information on the effectiveness of monetary incentives in expanding HIVST secondary distribution among MLWH. The findings of this trial will contribute to implementing HIVST secondary distribution services among MLWH in China and facilitating HIV case identifications.

Exploring the long-term sequelae of childhood sexual abuse on risky sexual behavior among Chinese transgender women. Front Psychol 2023; 14:1057225. [PMID: 37123291 PMCID: PMC10140497 DOI: 10.3389/fpsyg.2023.1057225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Accepted: 03/13/2023] [Indexed: 05/02/2023] Open
Abstract
Introduction Childhood sexual abuse (CSA) is a hidden but serious public health issue that can lead to a series of behavioral consequences and health problems in adulthood. It has been well documented that transgender women (TGW) have a high prevalence of CSA victimization. Moreover, risky sexual behaviors are also widespread among TGW; nevertheless, research investigating the associations between CSA victimization and risky sexual behaviors in TGW represents a gap in the literature. Methods Our research was carried out mainly in Shenyang of China from November 2018 to January 2019. Sociodemographic characteristics, as well as information on participants' HIV awareness and sexual behaviors, were collected through face-to-face interviews. The impact of CSA was examined through hierarchical logistic regression, adjusted for sociodemographic factors and HIV awareness. Results In the sample of 247 adult TGW, 14.2% of them had a CSA history. In the previous 6 months, 30.8% of the participants reported condomless anal intercourse (CAI) and 38.5% of them had multiple sexual partners (MSP). The findings demonstrated that TGW with CSA history were more likely to take part in CAI (p = 0.001, OR = 4.252) or have MSP (p = 0.004, OR = 3.260) in adulthood. Furthermore, HIV knowledge was not a predictor of CAI or MSP, but higher HIV risk perception was associated with a greater probability of CAI. Conclusion Transgender women with a history of CSA were more prone to engage in CAI and have MSP in China.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10185. [PMID: 36011822 PMCID: PMC9407807 DOI: 10.3390/ijerph191610185] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/07/2022] [Accepted: 08/15/2022] [Indexed: 06/15/2023]
Abstract
(1) Background: Men who have sex with other men (MSMs) are at high risk of being infected by the human immunodeficiency virus (HIV) in western China. Pre-exposure prophylaxis (PrEP) is an efficient way to prevent HIV transmission. However, adherence is the most vital determinant factor affecting PrEP effectiveness. We conducted a study based on the Health Belief Model to explore factors that predict adherence to PrEP among a cohort of 689 MSMs in western China. (2) Methods: We assessed perceived susceptibility, severity, benefits, barriers, self-efficacy, cues to action, and HIV-preventive behavior through a cross-sectional survey. (3) Results: PrEP self-efficacy was directly associated with PrEP behaviors (β = 0.221, p < 0.001), cues to action were directly associated with PrEP behaviors (β = 0.112, p < 0.001), perceived benefits were directly associated with PrEP behaviors (β = 0.101, p < 0.001), and perceived susceptibility was directly associated with PrEP behaviors (β = 0.117, p = 0.043). (4) Conclusion: Medication self-efficacy, perceived susceptibility, and cue to action structures are predictors of the MSMs’ HIV-preventive behavior in western China. These results will provide theoretical plans for promoting PrEP adherence in MSMs.

Abstract
Transgender women (TGW) worldwide report disproportionate violence victimization, depression and condomless anal intercourse (CAI), but the mechanism of the coexistence remains unclear. Using snowball sampling, we recruited 198 self-identified TGW in Shenyang, China between April 2017 and July 2017, and conducted confidential questionnaire survey among them. Positive HIV status was reported by 49 (24.7%) participants. 117 (59.1%) reported at least one type of lifetime violence victimization, with transactional sexual partners being the main violence perpetrators. 108 (54.5%) reported mild to severe depression. 105 (53.0%) reported having CAI with their sexual partners during the last 6 months. Path analysis showed that the association between participants' violence victimization and CAI was fully mediated by their depression (indirect effect: 0.083, p = 0.014; direct effect: 0.137, p = 0.121). We suggest to incorporate violence screening and prevention and mental health services into intervention strategies to prevent CAI among Chinese TGW.

Association between Psychological Factors and Condom Use with Regular and Nonregular Male Sexual Partners among Chinese MSM: A Quantitative Study Based on the Health Belief Model. BIOMED RESEARCH INTERNATIONAL 2020; 2020:5807162.

Abstract
Objective The Chinese men who have sex with men (MSM) population is suffering from a high HIV infection rate owing to unprotected anal sex. The Health Belief Model (HBM) has been proven to be an effective frame associated with behavior maintenance. Based on HBM, we analyzed the beliefs associated with consistent condom use behavior with regular and nonregular partners among MSM to better provide targeted interventions and services. Methods A study was conducted in Sichuan Province, China, from November 2018 to April 2019, and 801 eligible participants were recruited by snowball sampling. Sociodemographic characteristics, AIDS-related characteristics, sexual behaviors, condom use behavior, and dimensions of HBM were investigated. Univariate, single multivariate, and summary multivariate models were employed to analyze the factors associated with consistent condom use. Results Of all participants, 39.1% and 53.6% had had anal sex with regular and nonregular partners in the last six months, respectively. Only 56.5% of them had used condoms consistently with regular partners, and only 60% of them had used condoms consistently with nonregular partners. When taking consistent condoms use with regular partners as the dependent variable, the dimensions of perceived threats (ORM = 1.28, 95% CI: 1.10, 1.49), perceived barriers (ORM = 0.70, 95% CI: 0.60, 0.82), self-efficacy (ORM = 1.23, 95% CI: 1.14, 1.32), and cues to action (ORM = 1.21, 95% CI: 1.02, 1.43) showed significant associations with the dependent variable. When taking consistent condoms use with nonregular partners as the dependent variable, the dimensions of perceived barriers (ORM = 0.77, 95% CI: 0.67, 0.89), self-efficacy (ORM = 1.22, 95% CI: 1.13, 1.32), and cues to action (ORM = 1.53, 95% CI: 1.30, 1.80) showed significant associations with the dependent variable. Conclusions More attention should be focused on how to decrease the obstructive factors of condom use, how to improve the confidence of condom use, and how to layout more cues to action to promote consistent condom use behavior with regular and nonregular partners during anal sex among Chinese MSM.

Abstract
China has updated its national guideline recommending antiretroviral therapy (ART) to all people living with HIV (PLWH) since 2016. This study was to investigate the prevalence of behavioral intention to initiate ART among HIV-infected men who have sex with men (MSM) with CD4 levels >350 cells/mm3, who had just become eligible to receive free ART in China. A cross-sectional survey was conducted among 262 eligible HIV-infected MSM who had never received ART. The theory of planned behavior (TPB) was used to guide the variable selection. The prevalence of behavioral intention to initiate ART was 69.9%. After adjusting for significant background variables, all five constructs of TPB were significantly associated with behavioral intention to initiate ART. These significant constructs were: positive attitudes (adjusted odds ratios, AOR: 1.14; 95% CI [1.06, 1.24]) and negative attitudes (AOR: 0.89; 95% CI [0.82, 0.97]) toward immediate ART initiation; perceived their significant others would support them to initiate ART immediately (perceived subjective norm; AOR: 1.14; 95% CI [1.03, 1.25]); perceived high proportion of PLWH having similar CD4 cell levels were on ART (perceived descriptive norm; AOR: 2.22, 95% CI [1.16, 4.24]); and being confident in initiating ART immediately (perceived behavioral control; AOR: 1.21; 95% CI [1.04, 1.39]). Prevalence of behavioral intention to initiate ART was high among this group of MSM. Effective health promotion is needed to translate behavioral intention into related action. TPB may be a useful framework for developing future health promotion increasing ART coverage in this group.

Abstract
BACKGROUND The Information-Motivation-Behavioral Skills (IMB) model has received consistent empirical support in the context of HIV prevention among various key populations, but not yet among transgender women (TGW). None effective interventions has been carried out among TGW so far to control their high prevalence of unprotected anal intercourse. The intent of the current study is to examine the application of the IMB model to clarifying the association between condom use correlates and condom use frequency among TGW in China. METHODS Using snowball sampling, we recruited 198 self-identified TGW in Shenyang, China from April 2017 to July 2017. Participants were required to complete a questionnaire assessing their background characteristics and IMB model constructs. Structural equation modeling (SEM) was conducted to demonstrate the utility of the IMB model. RESULTS The consistent condom use (CCU) rate was 47.0%. Results of SEM indicated that HIV-preventive motivation (comprising condom use attitude and subjective norms; β = 0.823, P < 0.001) and behavioral skills (including condom use skills and self-efficacy; β = 0.979, P = 0.004) were related to more frequent condom use, whereas HIV knowledge was unrelated to condom use (β = 0.052, P = 0.540). CONCLUSIONS The low CCU rate suggested that TGW in China were at high risk of HIV infection and transmission and a key intervention population. HIV-preventive interventions for this population should focus on enhancing motivation and strengthening behavioral skills to increase condom use frequency and reduce HIV infection.

Abstract
Maternal HIV disclosure to children is beneficial for both mothers and children. A cross-sectional survey was conducted to investigate the prevalence of maternal HIV disclosure to at least one living child aged > 5 years among 292 HIV-infected mothers in Guangxi Province, China. Among all participants, 45.2% had self-disclosed their HIV positive sero-status to at least one living child aged > 5 years. After adjusting for the significant background variables, participants self-reported health professionals in governmental antenatal care clinics had discussed with them about maternal HIV disclosure (adjusted odds ratios, aOR: 5.85), had received counseling services (aOR: 7.84) or support (aOR: 8.75) from these health professionals when making decision on maternal HIV, and perceived higher empathy of these health professionals (aOR: 1.09) were more likely to have reported maternal HIV disclosure. Instrumental and affective interactions between health professionals and HIV-infected mothers were important facilitators of maternal HIV disclosure.

Abstract
People living with HIV/AIDS (PLWHA) often face significant stress, ranging from perceiving identity changes to encountering barriers to daily health behavior engagement. To manage these experiences, many people use positive reappraisal coping (including benefit finding and perceiving growth). Effective coping is highly important for PLWHA; stress reduction has salutary effects on multiple indicators of health. The present systematic review, conducted in PubMed, PsycINFO, and CINAHL, synthesises findings from 33 studies of PLWHA, addressing effects of positive reappraisal on health-related outcomes for adults living with HIV as a chronic illness. Studies were evaluated based on methodological considerations, measurement of key variables, and implications for specific aspects of health. Results suggest that positive reappraisal is often beneficial when dealing with the implications of a potentially traumatic HIV diagnosis on one's identity, although effects may be contextually bound. Implications of these findings are reviewed, emphasizing the importance of positive reappraisal for enhancing health promotion and self-management of HIV. Although the present review is limited by inclusion of multiple disparate outcomes and exclusion of non-English-language articles, these findings inform a comprehensive model of direct and indirect effects of positive reappraisal on emotional, functional, physiological, and behavioural aspects of health useful for guiding future research.

JMIR Public Health Surveill 2019; 5:e13083. [PMID: 31271148 PMCID: PMC6636239 DOI: 10.2196/13083] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2018] [Revised: 05/02/2019] [Accepted: 06/03/2019] [Indexed: 11/23/2022] Open
Abstract
Background Pre-exposure prophylaxis (PrEP) is currently an important tool for HIV prevention, especially in communities with higher risk of infection, notably men who have sex with men (MSM). To date, PrEP has remained generally unavailable in many cities around the world. In the planning of strategies for PrEP targeting MSM, community assessment is crucial to understand members’ responses to the new intervention. Objective Awareness and acceptance are 2 different but intricately linked contexts of PrEP. The aim of this study was to identify the determinants of awareness and acceptance of PrEP among MSM and to delineate their interrelationships in Hong Kong where PrEP services have not been developed. Methods A Web-based questionnaire survey was administered in light of the popularity of the internet as a platform for information and networking in the MSM community. Factors associated with PrEP acceptance and awareness were separately analyzed, and their predictors were subsequently tested by multivariate logistic regression. Associations between acceptance and awareness of PrEP were examined by factor network analysis. Results Between August and September 2016, results from a total of 453 HIV-negative MSM were analyzed. Half (49.7%, 225/453) of the respondents were aware of PrEP, and 78.3% (355/453) would consider using PrEP when it becomes available. Awareness of PrEP was associated with recent (P=.01) and ongoing (P=.04) use of psychotropic drugs for sex (chemsex). MSM who used online forums to seek sex partners had lower awareness (P=.04) than those visiting physical venues for sex networking. MSM who accepted PrEP were more likely users of internet channels for sex networking (P=.049), especially location-based social network apps (P=.04). MSM accepting PrEP were more concerned about their partners’ HIV status (P=.002), history of sexually transmitted infections (P=.01), condom use (P=.02), and HIV testing behavior (P=.02). Multivariate logistic regressions revealed that PrEP awareness was related to one’s networking pattern, whereas its acceptance was associated with inclination to self-protect from HIV. Factor network analysis highlighted the importance of chemsex, which was linked by over half of the edges, whereas the rest were contributed by HIV testing behaviors. Conclusions In Hong Kong, the overall awareness among MSM toward PrEP was only moderate but their acceptance was higher. Targeting MSM with chemsex behaviors through Web-based platforms and parallel development of tailored HIV testing services are important when introducing PrEP in the community.

Abstract
BACKGROUND The number of men who have sex with men (MSM) living with human immunodeficiency virus (HIV) in China has increased rapidly and thus immediate highly active antiretroviral therapy (HAART) after diagnosis was implemented as a strategy to reduce the HIV transmission. METHODS MSM who were diagnosed with HIV and received HAART between 2013 to 2015 in Xi'an were divided into three groups (>350, 200-350, and <200 cell/μL) according to their baseline CD4+ T cell count. The time of follow-up was calculated from the first date of receiving HAART to December 31, 2016. The CD4+ T cell count was detected with 1 week before or after HAART. The plasma viral loads were tested after 1, 2, and 3 years of treatment. RESULTS Of 1442 subjects who received HAART, 690 (47.9%) cases were in >350 cell/μL group, whereas 400 (27.7%) cases and 352 (24.4%) cases were in the 200-350 cell/μL group and <200 cell/μL group, respectively. After 1 year of treatment, the viral suppression rate in the <200 cell/μL group was 91.1%, which was significantly lower than the other two groups. The logistic regression results show that the >350 cell/μL group and 200-350 cell/μL group predicted higher viral suppression rates. CONCLUSIONS Baseline CD4+ T cell count more than 350 cell/μL can improve viral suppression among MSM living with HIV. Furthermore, to reduce the transmission risk, the treatment compliance of people living with HIV with high CD4+ T cell levels should be improved, and their diagnosis to the treatment time should be decreased.

JOURNAL OF SEX & MARITAL THERAPY 2019; 45:339-349. [PMID: 30703336 DOI: 10.1080/0092623x.2018.1526835] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/09/2023]
Abstract
This study was to investigate the prevalence and associated factors of inconsistent condom use with HIV-discordant regular male sex partners (RP: defined as their husband or steady boyfriends) in the last six months among HIV-infected women in China. We interviewed 256 HIV-infected women who currently had at least one HIV-discordant RP and had had sexual intercourse with such RP since diagnosis. The prevalence of inconsistent condom use with HIV-discordant RP was 48.4%. Associated factors included perceptions related to condom use and perceived competence in communicating with HIV-discordant RP regarding condom use.

A cross-sectional study of the relationship between sexual compulsivity and unprotected anal intercourse among men who have sex with men in shanghai, China. BMC Infect Dis 2018; 18:465. [PMID: 30219033 PMCID: PMC6139151 DOI: 10.1186/s12879-018-3360-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Accepted: 08/23/2018] [Indexed: 11/13/2022] Open
Abstract
Background HIV prevalence among men who have sex with men (MSM) in China is rising rapidly, and unprotected anal intercourse (UAI) is associated with HIV transmission. Recent research has shown that associations between UAI and other factors can differ according to the type of sex partners, including regular partners and casual partners. This study aimed to explore the relationship between sexual compulsivity and UAI according to partner type among MSM in Shanghai, China. Methods A cross-sectional study was conducted among 547 MSM from four districts in Shanghai, China. All participants were recruited using snowball sampling. The Sexual Compulsivity Scale was used to evaluate participants’ sexual compulsivity. Multivariable logistic regression was used to identify factors associated with sexual compulsivity and UAI. The mediation effects of substance use before sex on the relationship between sexual compulsivity and UAI were tested through mediation analyses. Results After adjusting for sociodemographic variables, sexual compulsivity was associated with overall UAI (adjusted odds ratios [AOR] = 1.039, 95% confidence intervals [CI] = 1.004–1.075), UAI with non-regular sex partners (AOR = 1.089, 95% CI = 1.033–1.148) and UAI with commercial sex partners (AOR = 1.185, 95% CI = 1.042–1.349). No significant association was found between sexual compulsivity and UAI with regular sex partners (AOR = 1.029, 95% CI = 0.984–1.077). Mediation analyses indicated that the relationship between sexual compulsivity and UAI was not mediated by either alcohol use before sex or drug use before sex. Conclusions The association between sexual compulsivity and UAI varies depending on the type of UAI partner. Therefore, individuals may engage in different types of UAI for different reasons, and tailored HIV cognitive–behavioral intervention programs are needed.
